Although there is some controversy regarding treatment approaches, especially related to the behavioral sequelae, we have hypothesized in other published work that it is characterized by the rapid onset of Reward Deficiency Syndrome (RDS) in children. We propose utilizing a multi-systems biological approach involving the coupling of genetic addiction risk testing and pro-dopamine regulation (KB220/POLYGEN®) to help induce “dopamine homeostasis” in patients with PANDAS, especially those with known DNA-induced hypodopaminergia. This case study examines a 12-year-old Caucasian male with no prior psychiatric issues who presented with a sudden onset of severe anxiety, depression, emotional liability, and suicidal ideation. The patient underwent genotyping and the genetic addiction risk score (GARS) testing, which revealed risk polymorphisms in the dopamine D2 (-DRD2/ANKK (Taq1A), OPRM1 (A/G), DRD3 (C/T), and MAOA (4R) genes. These polymorphisms have been linked to hypodopaminergia. The patient was subsequently placed on research ID-KB220ZPBMPOLY (POLYGEN®), and albeit the possibility of bias, based upon self and parental assessment, a marked rapid improvement in psychiatric symptoms was observed. In the second phase of treatment (102 days utilizing KB220), the patient received standard antibody testing, which was positive for Lyme. Antibacterial therapy started immediately, and KB220z was discontinued to provide a wash-out period. A monotonic trend analysis was performed on each outcome measure, and a consistently decreasing trend was observed utilizing antibacterial therapy. Our recommendation, albeit only one case, is to utilize and further research a combined therapeutic approach, involving precision-guided DNA testing and pro-dopamine regulation along with antibacterial therapy, as well as glutathione to address offensive enhanced展开更多

PANDAS has been known to cause a sudden onset of reward deficiency syndrome (RDS). RDS includes multiple disorders that are characterized by dopaminergic signaling dysfunction in the brain reward cascade (BRC), which may result in addiction, depression, avoidant behaviors, anxiety, tic disorders, and/or OCD. According to research by Blum et al., the dopamine receptor D2 (DRD2) gene polymorphisms are important prevalent genetic determinants of RDS. The literature demonstrates that infections like Borrelia and Lyme, as well as other infections like group A beta-hemolytic streptococcal (GABHS), can cause an autoimmune reaction and associated antibodies target dopaminergic loci in the mesolimbic region of the brain, which interferes with brain function and potentially causes RDS-like symptoms/behaviors. The treatment of PANDAS remains controversial, especially since there have been limited efficacy studies to date. We propose an innovative potential treatment for PANDAS based on previous clinical trials using a pro-dopamine regulator known as KB220 variants. Our ongoing research suggests that achieving “dopamine homeostasis” by precision-guided DNA testing and pro-dopamine modulation could result in improved therapeutic outcomes.展开更多

文摘Emerging adulthood(EA)is a critical stage of life to develop and sustain a healthy lifestyle,which is also a time of vulnerability to poor physical and mental health outcomes.In this study,we conducted a path analysis(N=1326)to examine associations among four dimensions of EA,levels of regular physical activity(PA),self-control,MPA tendency and irrational procrastination.Results found:1)higher levels of PA predicted both MPA tendency(β=−0.08,95%CI:−0.11 to−0.06,p<0.001)and irrational procrastination(β=−0.01,95%CI:−0.17 to−0.008,p<0.01)indirectly via self-control;2)Instability(β=0.13,95%CI:0.08 to 0.18,p<0.01)and Responsibility(β=−0.06,95%CI:−0.10 to−0.08,p=0.03)exerted direct effects on irrational procrastination and Instability also indirectly predicted irrational procrastination via MPA tendency(β=0.03,95%CI:0.02 to 0.05,p<0.01).These findings proved that perceived features of EA are linked to behavioral problems and supported that regular PA plays a crucial role to protect mental health.

文摘Populations experiencing negligible predation pressure are expected to evolve higher behavioral activity.However,when sexes have different expected benefits from high activity,the adaptive shift is expected to be sex-specific.Here,we compared movement activity of one cave(lack of predation)and three adjacent surface(high and diverse predation)populations of Asellus aquaticus,a freshwater isopod known for its independent colonization of several caves across Europe.We predicted 1)higher activity in cave than in surface populations,with 2)the difference being more pronounced in males as they are known for active mate searching behavior,while females are not.Activity was assessed both in the presence and absence of light.Our results supported both predictions:movement activity was higher in the cave than in the surface populations,particularly in males.Relaxed predation pressure in the cave-adapted population is most likely the main selective factor behind increased behavioral activity,but we also showed that the extent of increase is sex-specific.

文摘Background:Proprioceptive accuracy refers to the individual’s ability to perceive proprioceptive information,that is,the information referring to the actual state of the locomotor system,which originates from mechanoreceptors located in various parts of the locomotor system and from tactile receptors located in the skin.Proprioceptive accuracy appears to be an important aspect in the evaluation of sensorimotor functioning;however,no widely accepted standard assessment exists.In this systematic review,our goal was to identify and categorize different methods that are used to assess different aspects of proprioceptive accuracy.Methods:A literature search was conducted in 5 different databases(PubMed,SPORTDiscus,PsycINFO,ScienceDirect,and SpringerLink).Results:Overall,1139 scientific papers reporting 1346 methods were included in this review.The methods assess 8 different aspects of proprioception:(a)the perception of joint position,(b)movement and movement extent,(c)trajectory,(d)velocity,and the sense of(e)force,(f)muscle tension,(g)weight,and(h)size.They apply various paradigms of psychophysics(i.e.,the method of adjustment,constant stimuli,and limits).Conclusion:As the outcomes of different tasks with respect to various body parts show no associations(i.e.,proprioceptive accuracy is characterized by site-specificity and method-specificity),the appropriate measurement method for the task needs to be chosen based on theoretical considerations and/or ecological validity.
文摘High transverse momentum(pT)particle production is suppressed owing to the parton(jet)energy loss in the hot dense medium created in relativistic heavy-ion collisions.Redistribution of energy at low-to-modest pT has been difficult to measure,owing to large anisotropic backgrounds.We report a data-driven method for background evaluation and subtraction,exploiting the away-side pseudorapidity gaps,to measure the jetlike correlation shape in Au+Au collisions at √sNN=200 GeV in the STAR experiment.The correlation shapes,for trigger particles pT>3GeV/c and various associated particle pT ranges within 0.5<pT<10GeV/c,are consistent with Gaussians,and their widths increase with centrality.The results indicate jet broadening in the medium created in central heavy-ion collisions.

文摘The slippery slope framework explains tax compliance along two main dimensions,trust in authorities and power of authorities,which influence taxpayers’compliance attitudes.Through frequentist and Bayesian analyses,we investigated the framework’s assumptions on a sample of 2786 self-employed taxpayers from eleven post-communist and non-post-communist countries doing business in five economic branches.After using scenarios that experimentally manipulated trust and power,our results confirmed the framework’s assumptions regarding the attitudes of the self-employed taxpayers;trust and power fostered intended tax compliance and diminished tax evasion,trust boosted voluntary tax compliance,whereas power increased enforced tax compliance.Additionally,self-employed taxpayers from post-communist countries reported higher intended tax compliance and lower tax evasion than those from non-post-communist countries.Our results offer tax authorities insights into how trust and power may contribute to obtaining and maintaining high tax compliance levels amid global economic challenges,downturns,and increasing tax compliance costs.
文摘Point defect quantum bits in semiconductors have the potential to revolutionize sensing at atomic scales.Currently,vacancy-related defects are at the forefront of high spatial resolution and low-dimensional sensing.On the other hand,it is expected that impurity-related defect structures may give rise to new features that could further advance quantum sensing in low dimensions.Here,we study the symmetric carbon tetramer clusters in hexagonal boron nitride and propose them as spin qubits for sensing.We utilize periodic-DFT and quantum chemistry approaches to reliably and accurately predict the electronic,optical,and spin properties of the studied defect.We show that the nitrogen-centered symmetric carbon tetramer gives rise to spin state-dependent optical signals with strain-sensitive intersystem crossing rates.Furthermore,the weak hyperfine coupling of the defect to their spin environments results in a reduced electron spin resonance linewidth that can enhance sensitivity.

文摘The 2-m aperture Chinese Space Station Telescope(CSST),which observes at wavelengths ranging from 255 to 1000 nm,is expected to start science operations in 2024.An ultra-deep field observation program covering approximately 10 deg2is proposed with supernovae(SNe) and other transients as one of its primary science drivers.This paper presents the simulated detection results of type Ⅰa supernovae(SNe Ⅰa) and explores the impact of new datasets on the determinations of cosmological parameters.The simulated observations are conducted with an exposure time of 150 s and cadences of 10,20,and 30 d.The survey mode covering a total of 80 observations but with a random cadence in the range of 4 to 14 d is also explored.Our simulation results indicate that the CSST can detect up to ~1800 SNe la at z <1.3.The simulated SNe la are then used to constrain the cosmological parameters.The constraint on can be improved by 37.5% using the 10-d cadence sample in comparison with the Pantheon sample.A deeper measurement simulation with a 300 s exposure time together with the Pantheon sample improves the current constraints on Ωmby 58.3% and ω by 47.7%.Taking future lager sets of nearby SN Ⅰa sample form ground-based surveys(i.e.,N~3400) into consideration,the constraints on ω can be improved by 59.1%.The CSST ultra-deep field observation program is expected to discover large amounts of SNe la over a broad redshift span and enhance our understanding of the nature of dark energy.
文摘Pediatric autoimmune neuropsychiatric disorders associated with group A streptococcal infections (PANDAS) is a concept that is used to characterize a subset of children with neuropsychiatric symptoms, tic disorders, or obsessive-compulsive disorder (OCD), whose symptoms are exacerbated by group A streptococcal (GAS) infection. PANDAS has been known to cause a sudden onset of reward deficiency syndrome (RDS). RDS includes multiple disorders that are characterized by dopaminergic signaling dysfunction in the brain reward cascade (BRC), which may result in addiction, depression, avoidant behaviors, anxiety, tic disorders, and/or OCD. According to research by Blum et al., the dopamine receptor D2 (DRD2) gene polymorphisms are important prevalent genetic determinants of RDS. The literature demonstrates that infections like Borrelia and Lyme, as well as other infections like group A beta-hemolytic streptococcal (GABHS), can cause an autoimmune reaction and associated antibodies target dopaminergic loci in the mesolimbic region of the brain, which interferes with brain function and potentially causes RDS-like symptoms/behaviors. The treatment of PANDAS remains controversial, especially since there have been limited efficacy studies to date. We propose an innovative potential treatment for PANDAS based on previous clinical trials using a pro-dopamine regulator known as KB220 variants. Our ongoing research suggests that achieving “dopamine homeostasis” by precision-guided DNA testing and pro-dopamine modulation could result in improved therapeutic outcomes.

文摘Little is known about the role of active school travel(AST)on mental health among adolescents.Thus,this study aimed to explore the AST-depression association among adolescents aged 12–15 years from 26 low-and middle-income countries(LMICs).Data from the Global School-based Student Health Survey were analyzed in 51,702 adolescents[mean(SD)age 13.8(1.0)years;49.3%boys).Both depressive symptoms and AST were assessed by a single question self-reported measure,respectively.Participants who reported having 5 days or above were considered as AST.Multivariable logistic regression analysis(accounting for sampling weights)was performed while controlling for gender,age,physical activity,sedentary behavior,and food insecurity,and a countrywide meta-analysis was undertaken.The prevalence of depressive symptoms and AST were 30.1%and 37.0%,respectively.Compared with those not having AST,adolescents with AST were less likely to have self-reported depressive symptoms(OR=0.88,95%CI:0.85-0.93)regardless of gender.Countrywide meta-analysis demonstrated that having AST versus not having AST was associated with 12%lower odds for depressive symptoms(OR=0.88;95%CI:0.82-0.94)but with a moderate between-country heterogeneity(I^(2)=59.0%).Based on large samples of adolescents from LMICs,it would be expected that AST may play a critical role in preventing adolescent depression worldwide.However,it is necessary to consider more country-specific factors when implementing AST-related mental health interventions.Future studies should adopt the solid study design to confirm or negate our researchfindings.

文摘Topological materials host robust properties,unaffected by microscopic perturbations,owing to the global topological properties of the bulk electron system.Materials in which the topological invariant can be changed by easily tuning external parameters are especially sought after.Zirconium pentatelluride(ZrTe_(5))is one of a few experimentally available materials that reside close to the boundary of a topological phase transition,allowing the switching of its invariant by mechanical strain.Here,we unambiguously identify a topological insulator–metal transition as a function of strain,by a combination of ab initio calculations and direct measurements of the local charge density.Our model quantitatively describes the response to complex strain patterns found in bubbles of few layer ZrTe_(5) without fitting parameters,reproducing the mechanical deformation-dependent closing of the band gap observed using scanning tunneling microscopy.We calculate the topological phase diagram of ZrTe_(5) and identify the phase at equilibrium,enabling the design of device architectures,which exploit the topological switching characteristics of the system.

文摘1)Background:The common factors which potentially contribute to the development of eating disorders and exercise dependence during early adulthood are still relatively unclear.The present study aimed to examine the role of BMI,body image inflexibility,and generalized anxiety in these two behavioral problems in a sample of college students.2)Methods:In total,878 habitual exercisers(58.1%male with BMI=22.12±2.39;41.9%female with BMI=20.55±2.21)with age of 20.09±1.76 years participated in this study.The main outcomes of interest are exercise dependence symptoms,eating disorders symptoms,body image inflexibility,and symptoms of generalized anxiety(as measured by Exercise Dependence Scale-Revised,Eating Disorder Examination-Questionnaire-Short Form,Body Image Acceptance and Action Questionnaire,and Generalized Anxiety Disorder-7,respectively).Pearson correlation,path analysis,and model fit information were tested.3)Results:After controlling for age,gender,and field of study,lower BMI was linked to more exercise dependence symptoms but this association was not statistically significant,while a greater BMI was significantly associated with a higher risk of developing eating disorders(β=−0.08,p<0.001).Moreover,higher body image inflexibility significantly and positively contributed to severe exercise dependence(β=0.26,p<0.001)as well as abnormal eating attitudes and behaviors(β=0.74,p<0.001).Furthermore,generalized anxiety is a significant contributor to exercise dependence symptoms(β=0.14,p<0.001)but not eating disorders symptoms.4)Conclusion:Based on our finding that body image inflexibility is a common risk factor for the development of exercise dependence and eating disorders,the prevention and treatment of these two disorders should involve the improvement of psychological flexibility.In addition,the individual with a higher BMI is more vulnerable to developing eating disorders,while those who have severer generalized anxiety symptoms should be given more attention when screening for exercise dependence.
文摘This short study aims to highlight contradictions in Ochsenius’s model for the basin-wide salt generation(Kara-Bogas bay desiccation).Without claiming completeness,and through numerous records cited from the specific literature,we attempt to point at crucial incoherencies in the classical evaporitic model.In our presupposition,these might have led our ancestors to conclude that basin-wide salt generation needs theoretically well-based models.This is emphatically true for the Transylvanian Basin,Romania.The selected records are basic for the specific topic.We checked their validity by logical reasoning and by literature references.As for salt generation,the classical Ochsenius model has been upheld for the generation of evaporates even though it has been known that there are records denying the exclusivity of the evaporation model.It has also been proven that deep-sea salt exists,yet terminology is reluctant to follow the new discoveries.If non-evaporitic salt generation exists,it entails that huge salt deposits may exist,which are not remnants of a desiccation process.These cannot be considered as part of the classical theory of evaporation.Former researchers left important but neglected records,which should have updated the model of Ochsenius by now.Well-documented historical observation uncovered some contradictions in the salt generation of the Transylvanian Basin,Romania.Hereby we list 10 important contradictions,which may reveal that the well-known theory of Ochsenius(i.e.drying of Kara Bogaz bay)ought to be challenged for the Transylvanian Basin.

文摘Urban areas differ from natural habitats in several environmental features that influence the characteristics of animals living there.For example,birds often start breeding seasonally earlier and fledge fewer offspring per brood in cities than in natural habitats.However,longer breeding seasons in cities may increase the frequency of double-brooding in urban compared with nonurban populations,thus potentially increasing urban birds’annual reproductive output and resulting in lower habitat difference in reproductive success than estimated by studies focusing on first clutches only.In this study,we investigated 2 urban and 2 forests great tit Parus major populations from 2013 to 2019.We compared the probability of double-brooding and the total number of annually fledged chicks per female between urban and forest habitats,while controlling for the effects of potentially confounding variables.There was a trend for a higher probability of double-brooding in urban(44%of females)than in forest populations(36%),although this was not consistent between the 2 urban sites.Females produced significantly fewer fledglings annually in the cities than in the forest sites,and this difference was present both within single-and double-brooded females.Furthermore,double-brooded urban females produced a similar number of fledglings per season as single-brooded forest females.These results indicate that double-brooding increases the reproductive success of female great tits in both habitats,but urban females cannot effectively compensate in this way for their lower reproductive output per brood.However,other mechanisms like increased post-fledging survival can mitigate habitat differences in reproductive success.

文摘In geology we often revise theoretical models;upon finding new evidence,such as the discovery of methane hydrates,the initial model will be challenged immediately.Hereby the authors put forward two postulates:1)There is a third,previously unexplored source of methane in the Transylvanian Basin,based on a new theoretical approach on methane hydrate formation;2)The dissociation of methane hydrates creates a strong chlorinity anomaly.Based on a recent analogy with the Black Sea basin model,we apply our statements to the Transylvanian Basin.Using direct and indirect indicators and the published system tract analysis,we claim that there are substantial grounds to believe that this model of methane hydrate formation applies to the Miocene Transylvanian Basin.Due to the increase of the geothermal gradient as a result of the volcanic activity from the Eastern Carpathians,the clathrates dissociated into methane and freshwater.This process of dilution resulted in a chlorinity anomaly that can be spotted in the formation waters of several gas fields from the Transylvanian Basin.
文摘The purpose of the research is to show that the general triangle can be replaced by the right-angled triangle as the 2D simplex, and this concept can be generalized to any higher dimensions. The main results are that such forms do exist in any dimensions;meet the requirements usually placed on an n-dimensional simplex;a hypotenuse and legs can be defined in these shapes;and a formula can be given to calculate the volume of the shape solely from the legs by a direct generalization of the Pythagorean Theorem, without computing the Cayley-Menger determinant.
